Abstract: A semiconductor device capable of handling high voltages includes a relatively thick epitaxial layer (42) the top surface of which defines a plurality of generally V-shaped grooves (50,52,54,56), a pair of the grooves (50,56) having positioned therebetwen active device regions (64, 72; 66, 74, 76; 68, 78), such pair of grooves acting as isolation regions including impurity regions (60,62) extending on both sides of the groove through the epitaxial layer to a lower layer (40). A pair of grooves (52, 54) inward of the first-mentioned grooves contact active regions of the device into which the V-shaped portions extend, again with each such V-shaped portion having impurity regions 80, 82 extending on both sides thereof. The impurity regions associated with the V-shaped grooves are formed simultaneously with other active regions of the device.

Abstract: An element protector control for protecting the electrically powered heating element of a kettle against overheating has primary and secondary (or back-up) modes of operation. The primary protection mode utilizes a dished, snap-acting bimetal (22) which is oriented so that the side of the bimetal which is con­vex when the blade is cold faces the heating element head (24), and the bimetal is held in close thermal contact with a rear surface of the element head. The bimetal determines the condition of a pair of switching contacts (32, 33) provided in the control. The bimetal is mounted in a carrier (21) which is spring biassed towards the element head and, for providing the secondary pro­tection mode, the carrier is formed of a thermoplastics material so that in the event of failure of the primary protection in an overtemperature situation so that the element temperature continues to rise, the carrier will collapse towards the element head, and the collapse of the carrier is arranged to disconnect the control from its power supply terminals.

Abstract: The actual resonant frequency of an ultrasonic horn is tracked actively while the horn is operating in a working environment, such as in a clinical analyzer where the horn is partly immersed in a liquid bath in which a series of liquid-filled cuvettes are passed near the horn to dissolve solid tablets in the cuvettes. The horn is driven initially by a signal of fixed amplitude but at a frequency which is varied between set limits about a nominal resonant frequency. Ultrasonic vibration waves of the horn are sensed and fed back for rectification and peak detection over the scan operation. The peak feed back level is held and a second scan is initiated with the drive signal at the same fixed amplitude. When the rectified feedback signal level substantially attains that of the held peak level, a comparison is determined and control logic acts to lock on the frequency at which the comparison was established for a given operating time period.

Abstract: Through-put of a bidirectional serial printer is increased by optimizing the print head's movement between print lines. Optimization is performed on a time basis rather than a distance basis. A deter­mination is made as to whether it is quicker to position the print head at the left or right end position of the next print line. The calculations account for current print head position, the relative end positions of the next print line, the length of the next print line, current print head speed, the various acceleration and deceleration times and the turn-around settling time for the print head.

Abstract: A cushion for motor vehicle seating or furniture comprises a flexible outer membrane or cover and a multi-hardness foam member, comprising foam regions of different foam hardness. The foam regions are bonded together along common boundaries and are bonded to the membrane at any boundary therewith, such bonding occurring during formulation of the foam member and employing the materials of which the foam member is made. The method generally comprises the steps of: (a) providing a flexible membrane having a cavity therein; (b) adding to the cavity in a predetermined sequence a plurality of formulations in liquid form which, when cured, provide a foam article having foam regions of different hardness; (c) and allowing the formulations to cure, bond together at any common boundary between for­mulations, and bond together at any common boundary between a formulation and the membrane. The method may include the further step of changing to the orientation of the membrane cavity to thereby affect the flow of one or more formulations and determine the shape of the foam region subsequently formed thereby.

Abstract: New alkoxytitanium(IV) chelates are distinguished in that they contain alkyl citrates as chelating agents. Like other titanium chelates, they retard the catalytic effect, known per se, of the titanium component in cross-linking reactions. When used in printing inks, the new chelates and their solutions in alcohol have the advantage that they have only a slight natural colour so that cause virtually no discoloration in the printing inks. A further advantage of the new chelates consists of the fact that they do not interact with phenol-based antioxidants so they can also be used for those printing inks which are applied to a polymeric substrate cotaining such antioxidants without discoloration occurring. The new chelates are used in printing inks based on nitrocellulose or other cellulose derivatives.

Abstract: A non-excavating method for surveying individual subsurface layer thicknesses and properties of a ground, such as a road or other sites, by obtaining propagation velocities of vibration energy of predetermined frequencies which propagates through the subsurface layers ranging from the top surface to at least a subgrade section. The thicknesses of individual subsurface layers covering the depths from the ground surface to the subgrade are determined from the differences of the propagation velocities of the vibration energy and identifying each of the propagation velocities with the average propagation velocitiy of the corresponding wave propagated through the subsurface ground having the depth equal to one half of the corresponding wavelength. The properties of the individual subsurface layers are also determined by utilizing the correlation between property values, such as bearing strength ratios, of the constituent materials of the layers and the propagation velocities of the vibration energy.
